Questionnaire supports life adjustment factors

When this option is selected, the confidence questionnaire adds a life adjustment factor to the failure mode. A life adjustment factor is a portion of an asset’s by-design life span, for example, one tenth of its original estimated life. Typically, a life adjustment factor is used to estimate asset lining’s remaining life based on its condition at the time of inspection. This information is used to track the asset’s degradation. You can specify whether the lowest or highest factor is used in the evaluation. For example, if the highest factor is used, when the analyst completes the questionnaire, APM takes the highest life adjustment factor from the answers. The factor is shown in the Details area of the failure mode’s Confidence tab.
